One day, two old men and a boy appeared in Gacel Shayah's camp in the Sahara. He, a noble inmouchar observing the millennial tradition of the desert, sheltered travelers. But he failed to protect them. People in dusty military uniforms violated the ancient hospitality law. They killed the boy and took one old man away. Gasel Shayah remembers the great commandment of the Tuareg people: your guest is under your protection. Therefore, he has to seek vengeance.
